Speciation

It increases the variety of life forms on Earth

It reduces the number of species

It prevents evolution

It stops natural selection

They must share a common chromosome number.

They must live in the same environment.

They must have the same color.

They must eat the same food.

Geographic isolation

Hybrid infertility

Behavioural isolation

Temporal isolation

The rapid diversification of a single ancestral line into various species adapted to different niches.

The extinction of species due to competition.

The process by which species migrate to new environments.

The gradual change of a species over time without diversification.

Allopatric speciation involves geographic isolation, while sympatric speciation does not.

Allopatric speciation is caused by behavioral isolation only.

Sympatric speciation requires a physical barrier.

Sympatric speciation cannot occur in plants.

Polyploidy increases the mutation rate in plants.

Polyploid offspring are not genetically compatible with their parents.

Polyploidy allows plants to survive in harsh environments.

Polyploidy reduces the number of chromosomes in offspring.

It involves two different species.

It results from hybridisation.

It always produces infertile offspring.

Both parents contribute unreduced gametes.

Has a tail

Has wings

Has a pouch

Is nocturnal

eDNA is genetic material released by organisms into the environment.

eDNA can be used to identify species without direct observation.

eDNA can only be found in water samples.

eDNA can last for days to weeks in the environment.
